SYSTEM FOR DAMAGE ANALYSIS OF BIOLOGICALLY RELEVANT MATERIALS IN ULTRA-HIGH SPEED DYNAMIC ENVIRONMENT
Abstract
SYSTEM FOR DAMAGE ANALYSIS OF BIOLOGICALLY RELEVANT MATERIALS IN ULTRA-HIGH SPEED DYNAMIC ENVIRONMENTThe purpose of this DURIP proposal is to acquire a multi-material 3D printer and a set of highspeed cameras equipped with infinitely corrective objective lenses and digital image correlation (DIC) technology to perform nanoscale damage analysis of biologically relevant materials (soft ansd hard) in ultra-high speed dynamic environments. Over the past several years, the PI Adnan has been investigating trauma-induced molecular level neuronal injury mechanisms and cavitation in biologically relevant soft materials. In collaboration with co-PI Taylor, who is an expert in 3D printing and structural optimization, the PI Adnan will use the proposed 3D printing system to build morphologically detailed biologically relevant soft and hard materials. Specimen prepared out of these materials will then be subjected to various types of dynamic events such as impact and directed energy exposure. The set of ultra-high speed cameras (frame rate as high as ten million frames per second or one frame per hundred nanosecond) will be used to record such extremely fast dynamic events. Moreover, by integrating these cameras with digital image correlation (DIC) platform, real-time deformation and strain in soft and hard materials will be obtained at the micron and nano-scale resolution. By placing cultured neuronal cell lines inside a 3D printed surrogate brain material, the effect of dynamic loading on living brain cells will be studied. In addition to directly supporting the PIs ongoing ONR funded research, the proposed system will provide timely support for UTAs initiatives involving the College of Engineering Makerspace, curriculum integration, and research thrusts. The proposed system will also benefit the PIs collaborative research with the Air Force Research Laboratory (AFRL) for effective prototyping of aerospace components using 3D printing and subsequent validation of multiphysics analysis models.With the ever-changing nature of improvised threats, the operational environments for the warfighters are becoming challenging every day. Our warfighters need to improve their ability not only to prevent, mitigate and treat injuries but also to assure agile maintenance of force readiness. For this, better interface between brain, sensing elements and protective equipment is critical. It is believed that the DURIP proposal will directly address ONRs mission towards augmented warfighter and operational endurance by quantifying and advancing warfighters close combat lethality and force readiness. As such, the DURIP proposal proposed here has direct relevance to ONRs Basic Biomedical program (Code 342, Dr. Timothy Bentley Program Manager and Deputy, Force Health Protection (FHP) Program).
